Product Description:

The MSK100B-0300-NN-M2-BP1-RNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Integrated with IndraDrive amplifiers, it supplies closed-loop torque and velocity control for packaging stations, gantry axes, and other position-critical machinery. Its role in automation is to transform commanded current into accurate rotary motion while preserving repeatability during rapid acceleration, deceleration, and holding modes. The motor is well suited for applications that require stable speed regulation together with precise positioning during frequent cycle changes.

Heat is dissipated by natural convection, so the housing removes thermal energy without fans or liquid circuits. A cast housing rated IP65 blocks dust and low-pressure water jets, allowing the motor to mount directly on machine frames outside sealed cabinets. The power connector is arranged on side B, and the output end carries a shaft with keyway that mates with standard couplings or pulleys. The housing uses increased concentricity to reduce radial runout when the size 100 stator is paired with precision gear stages. Position feedback comes from an optical encoder that communicates through EnDat2.1 and provides 2048 signal periods per revolution, while the multiturn absolute function stores full revolutions without batteries so absolute position is available at startup.

An electrically released brake develops 32 Nm of static torque, which helps hold vertical or suspended loads in place during power loss. Thermal protection is supported by class 155 insulation and an ambient operating range of 0 to 40 °C. Winding code 0300 identifies the conductor size and coil pitch used for the motor’s electrical characteristics, while motor length B provides additional active iron for medium-inertia torque demand. This arrangement supports accurate position retention, dependable stopping behavior, and continuous operation without auxiliary cooling hardware.
